I just bought mine today and spent $630 (and there is one that is not out yet, so that will be another $40 or so). I only bought the required books, not any of the ones that were just recommended--I figure I will be able to determine pretty quickly whether or not I'll need those once classes start. I was able to get about half of them used...had I bought them all new, it would have been at least $150 more. I probably could have gotten some of them cheaper by buying used books on amazon or abebooks, but I was nervous about buying used books sight unseen (other people's writing/highlighting drives me nuts). On the flip side, probably about half of these books are ones I will be using all year, so I don't expect book costs to be so high next semester. If you are going to buy used online, I would do so soon, as it looks like things are starting to get picked over.
